To all whom it may concern:

Be itzknown; that I, CARL GUsTAE SWEBI- Line, a citizenof the UnitedStates, residing at New I-laven, in the county of New Haven and State ofConncticuhhave invented. a new and useful Improvement in TakedownFirearms, of which the following is a specification.

to firearms and gun in which the barrel portion and stock portion may beseparated for convenlenceln paclnnga-nd transportation, such as 1sd1sclosed in the patent to Swebilius 'etal.

1,110,837 A gun of-this type comprises a barrel portion, a stockportion, a separable receivercomprising one part including a top plateand two depending side plates rigidly connected with the barrel,and'another part inchn'ling a tang arranged to be located Wltllin thetwo side plates of the firstementioned part. saidtang being rigidlyconnectedwith the stock, a separable hinge for operatively connectingthe tworeceiver parts at one end of the receiver, and a bolt foroperatively connecting said parts at the other end of the receiver. Thisbolt is projected from the tang-carrying part of the receiver into asocket in the top of the main portion thereof by means of a suitablespring and is provided with a button for retracting it. hen the bolt isseated in the socket it locks together the two parts. The continuoustale ing down and putting together of the gun sometimesresults in asuflicient wearing of the head of the bolt to allow a slight play of thestock and barrel relatively to each other.

It is the primary purpose or object of this invention to provide asimple and efficient means for overcoming such play when it developeswithout it. being necessary to take the gun to pieces or to replace thebolt. This is accomplished by making the bolt in two parts and providingmeans, accessible from the ertposed head of the bolt, for adjusting thebolt proper relative to the remaining portion or slide.

it-herobjects of the invention will be apparent as the descriptionthereof proceeds Tn the drawings,

Fig. 1 is a side elevation of a gun constructed in accordance with myinvention, part thereof being in section;

Fig. 2 is a perspective detail view;

'Fig. 3 is asection on the line 33 of Fig. 1.

The receiver of the gun, open at the bottom and rear, is designated bythe numeral 1 and the stock by 2. Rigidly carried by the stock is thetang 3 having at its forward end a hook at which is adapted to engagewith the pin 5 extending between the side walls ef the receiver at itsforward end.- The tang is of such a width throughout its length that itfits between the walls of the receiver and forms the bottom thereof. Attherear end of the'tang is an inclined abutment, or rein- I force 6suitably designed to engage the rear end of the-receiver when theparts'are assembled; F rom the upper end of the abutment 6 there extendsrearwardly a member 7. In a suitable recess 8. in this member there isreciprocatively mounted a bolt 9, having ahead adapted to seat in acoacting socket 10 in the rear upper end of the re-' ceiver. V g

The rear end of the bolt is forked and between the arms 11 thereof isslidably mounted a rod 12 in which is the transverse groove 13. Betweenthe rear end of the recess 8 and a suitable abutment on the rod 12 is aspring 14 tending to force the rod 12 forward. Carried in the forwardend of the bolt and extending between the arms 11 is the rotatablemember 15, the inner end of which is screw-threaded and engages acorrespondingly threaded socket in the forward end of the rod 12. Thismember is held against motion longitudinally of the bolt in any suitablemanner.

Near its rear end the recess 8 is extended to form a vertical slot. Thelever 16 is pivotally mounted in the bottom portion of this slot andextends through the groove 13 in the rod 12 up into the upper portion ofthe slot. A slide 17 having depending lugs 18 extending into the upperportion of the slot is provided. Extending between the lugs 18 is a pin19 to fit into the slot 20 in the upper part'of the lever 16. The slideis held in place by a pin 21 passing through the slot 22 therein.

In order that the position of the slide for the safety lock need not bechanged. a slot 23 may be cut therethrough to allow the passage of themember 15.

The upper face of the bolt is tapered slightly so that when the hook 4:is engaged socket a snflicient depth to holdthe parts firmly in placebut not to project so far but that it will be automatically retracted byroation of the two portions of the gun when being assembled. it happens,however, that this condition cannot be indefinitely maintained becauseof the wear on the head of the bolt a'l terfa considerable usage. Thiswearing will allow the parts of the receiver to move relative to eachother and destroy the desired rigidity of the parts. The abovedescribedarrangement remedies thislcondition. When the parts begin to get loosethe screw 15 is'turned sn'l'licientl-y to allow the I head of the bolt'to protrude slightly further or until the desired rigidity'cisagainwattainedi- What I claim is: r 1. In a take-down firearm, a barrel;a S stock, a receiver'comprising twoportions, a separable hinge forconnecting the two re cei er portions at one en l, a bolt foroperativcly connecting said portions at theother. end, means foroperating the bolt, "and 3 means for varying the position of the boltrelative to said last-named-means; V

2. In take-down firearm, abarrel, a stock, a receiver comprising twoportions, a separable hinge for connecting the two -re-.

5 ceiver portions at one end, a bolt for operati vely It'is essential'that the head et the bolt project far enough to enter into theconnecting said portions at the other end, a slide, and means connectingthe slide andnbolt whereby the position of the bolt relative to theslidemay be varied.

3. In a take-down firearm, a barrel, a

'stoclna receiver comprising two portions, a separable hinge forconnectlng the two receiver portions at one end, a bolt for operativel yconnecting said portions at the other end, a slidejh-aving a threadedsocket therein, and a screw carriedfby said bolt to engage in saidthreaded socket.

t. In a takedown firearm, a barrel, a stock, a receiver comprising twoportions, a separable hinge for connecting the two receiver portions atone end, a bolt for operatively connecting said portions at the otherend, a slide, means connecting the slide and bolt whereby the positionof the bolt rela tive tothe, slide be varied, and means for normallymaintainingsaid slide in 0116 position. 9 1

5. In a take-down firearm, a barrel, a stocln'areceiver comprising twoportions, a separable hinge for connecting the two receiver portions atone end, a bolt for operatively connecting s'aidportions at the otherend, a slide, means connecting the slide and bolt' whereby the positionof the. bolt rela: tive to theslide may be varied, means for normallymaintaining said slide in one position,.fancl means for moving saidslide from its, normal position.
